摘　　要：应用裂解-气相色谱质谱（PY-GC／MS）分析技术，分析了麦秆在900℃时闪速裂解产物的主要组分及其相对含量。分离并确认出分子量在40-650范围的39种化合物，主要是烃类含氧有机化合物（包括酚、醛、酮、酯、醇、酐、酸类）和少数高分子烷烃。闪速加热奈件下，在总离子流图（TIC）上各特征裂解产物的出峰时间明显提前，为生物质固体废物资源化处理利用提供了基础资料。Pyrolysis-gas chromatagraphy/mass spectrometry （PY-Gc/MS） was used to analyse the pyrolysis products of wheat straw after flash heating to 900℃. 39 organic compounds were identified and their contents were isolated, whose molecular weight were in the range of 40 to 650. These compounds were mainly oxy-hydroearbon derivatives, including phenols, aldehydes, ketones, esters, alcohols, anhydrides and acids, and a few of high molecular weight paraffins. By flash pyrolysis, the peak times of the characteristic products in TIC were shortened, which provided basic data for the utilization of solid wastes of biomass resources.
